Figure 9. Structure of power dispatching data network
In above application scenarios, there are two strategies for uploading
new block information: one is that the plant/substation regularly upload
new block information to dispatch center, and this strategy can be
realized by utilizing the automated timing devices installed in
plants/substations. When the counter of timing device reaches a
specified value, it triggers an interruption to upload block
information. Another strategy is that local dispatch sends data summon
request to plants/substations, and the corresponding plants/substations
upload new block information immediately after receiving such summoning
message. Under either strategy, once the event to upload new block
information is triggered, P-PoW algorithm would instantly stop the
real-time data filling and signature iterative calculation progress, and
assembles the block header. Then, new block information is sent to local
dispatch center as soon as possible.
